X-Band DSCS Reflector Antennas

Small aperture military satellite communications
antennas in the 3 - 6 foot diameter class are available
from Seavey Engineering. They operate in the 7.25 - 7.75 GHz downlink frequency band
with right-hand circular polarization and 7.9 - 8.4 GHz in the uplink band with left-hand circular polarization.
All antennas are equipped with an elevation/azimuth pipe mount and CPR-112G waveguide flanges.
Transmit antennas can handle up to 1 KW RF power.
